NOTES: (1) dBFS refers to dB below Full-Scale. (2) Percentage accuracies are referred to the internal A/D converter Full-Scale Range of 4Vp-p. (3) To assure
DNL and no missing code performance, see timing diagram footnote 2. (4) IMD is referred to the larger of the two input signals. If referred to the peak envelope
signal (
≈
0dB), the intermodulation products will be 7dB lower. (5) No “rollover” of bits.
